In the last few weeks immigration has popped back on the public’s radar as an issue to follow. From the President’s June 15th announcement that his administration would grant deferred action to DREAM Act-eligible youth, to the recent Supreme Court ruling in Arizona v. United States, to candidates’ efforts to court the sought-after burgeoning Latino vote, the policy and politics of immigration aren’t far from the front pages.
